27: =head1 DESCRIPTION
28:
29: Perl access to the telnet interface on Trango Foxes, SUs and APs.
30:
1.20 andrew 31: Another handy feature is that it will parse the output from certain
32: commands that is in the format "[key1] value1 [key2] value2" and put
33: those in a hashref that is returned. This makes using the output from
34: things like sysinfo very easy to do.
